KL3204 | Bus Terminal, 4-channel analog input, temperature, RTD (Pt100), 16 bit
The KL3204 analog input terminal allows resistance sensors to be connected directly. The Bus Terminal’s circuitry can operate the sensors using 2-wire connection techniques. Linearization over the full temperature range is realized with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminals standard settings are: resolution 0.1°C in the temperature range of Pt100 sensors. The error LEDs indicate sensor faults (e.g. a broken wire). The KL3204 version combines four channels in one housing.
